Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiment wholely.Based on this
Embodiment in invention, those of ordinary skill in the art are not under making creative work premise, and obtained is every other
Embodiment, broadly falls into scope.
The core of the present invention is to provide a kind of vacuum boiler and to the method for vacuum boiler vacuum pumping, Apparatus and system.
In order to make those skilled in the art be more fully understood that the present invention program, below in conjunction with the accompanying drawings and detailed description of the invention
The present invention is described in further detail.
Embodiment one
The flow chart of a kind of method to vacuum boiler vacuum pumping that Fig. 1 provides for the present invention.As it is shown in figure 1, to vacuum
The method of boiler vacuum pumping includes:
Step S10: in the case of adding the water of scheduled volume in combustor and valve closing and boiler, send out to combustor
Send the heating instructions of water in heating boiler.
Closing combustor and valve, add the water of scheduled volume in boiler, combustor begins to warm up the water in boiler.In combustion
During water in burning machine heating boiler, enter step S11.Wherein, the interposition on boiler wall is equipped with visor, for the ease of
Observing, scheduled volume is to visor 1/2, it is important to note that scheduled volume is not limited in this numerical value in the present invention.
Step S11: the water temperature value that monitoring temperature sensor in real time sends, when water temperature value arrives the target temperature value set
Time, the stopping heating instructions of the water stopped in heating boiler is sent to combustor.
Temperature sensor is the temperature value of water in measuring boiler, in being embodied as, can be arranged by target temperature value
It it is 99 DEG C, by the water temperature value in temperature sensor measurement boiler, when water temperature value arrives the target temperature value set, combustor
Stop the water in heating boiler, now enter step S12.Wherein target temperature value is 99 DEG C, it is important to note that this
Bright middle target temperature value is not limited in this numerical value.
Step S12: send the open command opening vacuum vent holes to electric controller.
Having corresponding valve in vacuum vent holes, electric controller is connected with valve, thus controls vacuum vent holes
Open and close.After water in combustor stops heating boiler, electric controller, when receiving open command, opens vacuum
Steam vent, the steam in boiler is discharged by vacuum vent holes.
Step S13: the force value in Real-time Collection boiler, when force value is less than the target pressure value set, to electronic
Controller sends the out code cutting out vacuum vent holes.
After vacuum vent holes is opened, gas can be discharged by the steam in boiler, and the pressure in boiler is gradually
Reduce.In being embodied as, the force value in pressure vacuum gauge Real-time Collection boiler on boiler, when force value is less than setting
During target pressure value, electric controller cuts out vacuum vent holes.As a kind of optimal way, target pressure value is set to 5KPa.Need
